Infrared thermometers(紅外溫度計(jì)), or temperature guns, have been widely used to detect(檢測(cè))the early symptoms of COVID-19. They allow us to measure(測(cè)量)temperatures quickly. How do these thermometers work?
They determine temperature by measuring the energy coming from your skin (皮膚). Everything in nature has molecules (分子) inside of it that are always moving around. This include our skin. The higher the temperature is, the faster the molecules move. The molecules give off infrared light while moving.
This kind of light can be focused or absorbed(吸收). The thermometers use a lens(鏡頭)to focus infrared light from the skin onto a detector called a thermopile(熱電堆). The thermopile absorbs the infrared radiation and turns it into heat. The electronic sensors inside the thermometers can measure the heat and read the temperature of the skin after making some calculations (計(jì)算).
However, you might sometimes find that the results aren’t always accurate (準(zhǔn)確的). It depend on how these devices are used. For example, how far away they are held from the body, how steadily they are held and for how long. Factors such as make-up and sweat will also affect the results.

Duncan Smith and Katie Schmidt both always wanted to be firefighters. Now, the two 16-year-olds have started their training at Wellington High School Fire Science Academy in the US.
At the Fire Science Academy, students learn how fire behaves, how to use firefighting tools, how to save people, and of course, how to put out a fire.
The academy recently received a fire truck that will help students become familiar with the trucks used by real firefighters, according to Mark Davis, a teacher at the academy.
“It’s an important part of the program,” Davis said. “It allows our students to understand the everyday tools used in the fire service. It also gives them a sense of pride to enter into public service.” The fire truck will also help students practice before taking the state firefighter test, Davis said.
Schmidt said she was interested in the opportunities the academy presented.“It was my decision to go into this program,” she said. “My dad has been in this service for almost 25 years and I wanted to follow in his footsteps and learn and understand what he goes through in his day-to-day life.”
“The academy is strict and students have to be comfortable with standing to attention for most of the day,” Davis said. “I like the discipline(紀(jì)律) aspect because I feel like a lot of high school students sometimes go the wrong way, and with this, it’s not possible,” Schmidt said.
